- unit's Exec procedure to execute DOS commands (including
- running other programs or batch files).

- This program keeps prompting you for a DOS command until
- you enter a blank line.

- When using Exec, make sure you specify a {$M} directive
- so the heap leaves some memory available for the child
- process.
